accelerating matrix multiply
Hi Tomas,
Can you share the full code for your benchmark, compiler options, and performance results so that I can try to reproduce them? There are a lot of variables that can affect the results. Private email is fine if it is too much for the mailing list.
I am measuring on Knight's Landing (KNL) that was released in November. KNL is not a co-processor so no offload is necessary. R executes

remotely picked-up extension keeps ringing
Hello,
As of today's cvs * snapshot I am able to pickup a ringing (sip) cisco
7960 with *8 but the extension then keeps ringing indefinitely, even
though I picked up the call.
Is this a known issue? Thanks,

Hi Martin,
Here is the program I used. I only generate 2 random numbers and reuse them to make the benchmark run faster. Let me know if there is something I can do to help--alternate

Fwd:[Vocal] Question about Cisco IP hard phones
Interesting notes on the 79xx series.
The 7920 is the wireless phone; not mentioned here.
For a more complete guide to Cisco's phones, see:

The 7902 is the "very inexpensive" Cisco phone, and it looks like it
will be SCCP (Skinny) only. Twiddling my thumbs here waiting for the

survreg (survival) reports erroneous results for left-censored data (PR#2287)
Full_Name: Tim Cohn
Version: 1.6.1
OS: Macintosh OS X
Submission from: (NULL) (130.11.34.250)
The Mac version of survreg does not handle left-censored data correctly (at
least the results are not what I get doing it other ways, and they are not the
same as I get running R 1.6.1 in Windows 98se; the Windows 98 results are
correct). On the windows version of R 1.6.1.

Hi Robert,
thanks for the report and your suggestions how to make the NaN checks
faster.
Based on my experiments it seems that the "break" in the loop actually
can have positive impact on performance even in the common case when we
don't have NaNs. With gcc on linux (corei7), where isnan is inlined, the
"break" version uses a conditional jump while the

accelerating matrix multiply
I am using R to multiply some large (30k x 30k double) matrices on a 64 core machine (xeon phi). I added some timers to src/main/array.c to see where the time is going. All of the time is being spent in the matprod function, most of that time is spent in dgemm. 15 seconds is in matprod in some code that is checking if there are NaNs.

Interpretation of davies.test() in segmented package
My data:
I have raw data points that form a logit style curve as if they were a time
series. Which is to say they form 3 distinct lines with 3 distinct slopes
in backwards z pattern. A certain class of my data looks essentially flat
to the eye with marginal oscillation. What is important to me is the x
value at which the state change is occurring, in other words, the break

At one location we have a user whose Polycom IP430 suffers from erratic

Debate: Shall some of Microsoft R Open Code be ported to mainstream R?
I think the thing that is missing is a simple way for end users on windows to replace blas/lapack libraries with MKL-a package that you install that puts the libraries in the right place.
Microsoft provides something for their distro, but we don't have the equivalent if you get R from cran.

Outbound Caller ID on PRI
We have just had an ISDN PRI service commissioned here in AU (using Powertel
as provider). I have called them and ensured that we have the ability to set
Caller ID on our service to any number in our 100 number block, and I have
been assured that everything is OK from their end (unlikely). Every time I
drop a sample.call in to /var/spool/asterisk/outgoing with the Callerid:

Cisco to asterisk termination with h323 and g729 finally works.
Hello,
I managed to terminate calls from cisco: as5300 and 7206 to asterisk over h323.
I tested both oh323 from inaccessnetwork and JerJers chan_h323.
I used 1.12.2 version of oh323 and 1.5.2 version of pwlib.
After latest changes from JerJer chan_h323.c works ok when receiving traffic
from ciscos. I havnt found any audio problems although I didnt send much
traffic.
Latest oh323 has some

We are using asterisk 0.4.0 on debian sid with Cisco 7960 and ATA186

All sip entries have:

Instead, the better alternative is to write another pass similar to
LoopUnrollPass.cpp (say LoopPeelPass.cpp) and add new option
-loop-peel. The new pass could use llvm::UnrollLoop()
